  • Trailblazer 251NT with LN-25 Feeder

    I recently acquired a LN-25 feeder for my 251NT. The feeder has the V/A control upgrade and is a 6 pin on the back of the feeder, is there a way to adapt this and make it work with the Miller 14 pin?

    Dont quote me on this but I don’t think so. A 12rc feeder would be an easier fit for you.

      The ln-25 manual I found says the remote voltage control option is a 10k pot. I think miller uses a 1k, but the input impedance seems quite high on the units I've poked at, and it's a voltage divider, so 10k is probably compatible. I don't have time to dig up a lincoln service manual and figure out the wiring - work has me way too busy lately. If the three pins on the pot are just wired to three pins on the plug, your adapter cable should be easy to make. You could also trivially modify the lincoln unit to have a miller knob and cable stuck in it.

        Or, you can sell it and pick up a 12Rc or a 12vs Miller feeder, plug in and go
